设计雇员Employee类,记录雇员的情况,包括姓名、年薪、受雇时间,要求定义MyDate类作为受雇时间,其中包括工作的年、月、日,并用相应的方法对Employee类进行设置。编写测试类测试Employee类。要求使用自己的包。 mypackage.employee; class MyDate{ private int year; private int month; private int day; public MyDate(int year,int month,int day){ this.year=year; this.month=month; this.day=day; } public int getYear(){ return year; } } public class Employee{ private String name; private double salary; private MyDate hireDay; public Employee(String name,double salary,MyDate day){ this.name=name; this.salary=salary; hireDay=day; } public void print(){ System.out.println(name+ ""+salary+""+hireYear()); } public int hireYear(){ return hireDay.getYear(); } } class TestEmployee{ public static void main(String [] args){ Employee a=new Employee("李明",20000,new MyDate(2000,10,1)); Employee b=new Employee("王强",24000,new MyDate(1995,8,12));

A. print();
B. print(); } }
